Debye‐Scale Bipolar Structures and Their Role in the Electron Trajectory Instability at the Bow Shock

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract A number of mechanisms have been suggested to operate within the terrestrial bow shock to redistribute energy contained in the incoming solar wind flow. The majority of mechanisms involve the generation of turbulence while some are based on particle motion alone.

Outer Radiation Belt Dynamics During the October 2012 Storm Revisited: Rapid Inward Radial Transport From a Dynamic Outer Boundary

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract Earth's outer radiation belt electron flux is highly variable and can be enhanced by over an order of magnitude over timescales less than one day, as observed during the October 2012 storm. Previous studies of this storm (e.g., Reeves et al., 2013, https://doi.org/10.1126/science.1237743) have invoked local acceleration to explain this ...

Development and Investigation of a Modification to Extend the Dynamic Range of Electrostatic Analyzers

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract Plasma populations within the solar system are distributed over a substantial range of densities, kinetic temperatures, and bulk velocities, from the solar wind to Earth's ionosphere. Measuring the full range of plasma conditions for some of these populations is difficult for current top‐hat electrostatic analyzers, let alone for multiple ...

Evaluating Multipoint Sampling of Global‐Scale High‐Latitude Electrodynamics by the Geospace Dynamics Constellation

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract The Geospace Dynamics Constellation (GDC) mission aims to investigate the dynamic coupling between the magnetosphere, ionosphere, and thermosphere by resolving key spatiotemporal processes at scales ranging from local to global. A key aspect is GDC's ability to reconstruct hemispheric‐scale high‐latitude electrodynamics with comprehensive ...

Different Transient Phenomena at the Edges of Traveling Foreshocks

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract Past kinetic simulations and spacecraft observations have shown that traveling foreshocks (TFs) are bounded by either foreshock compressional boundaries (FCBs) or foreshock bubbles (FBs). Here we present four TFs with a different kind of structure appearing at one of their edges.
